the essential oils, isolated by hydrodistillation from the leaves, seeds and rhizomes of heracleum sprengelianum (wight and arnott), collected from the western ghats of peninsula india, were analyzed by gas chromatography (gc) and gas chromatography coupled to mass spectrometry (gc–ms). the antioxidant property of these oils was tested, with and without peroxidation inducer, through the egg yol...

BACKGROUND Several plant extracts from Rutaceae family are currently used to the management of sickle cell disorder (SCD) in the African. Few reports have shown that extracts from Zanthoxyllum or Fagara genus demonstrated anti-sickling property. This study investigates the in vitro antisickling and antioxidant properties of extracts from Zanthoxyllum heitzii. METHODS The sickling of red blood...

This study is aimed at assessing the inhibitory effect of teas on key enzymes (α-amylase and α-glucosidase) linked with type-2 diabetes and their antioxidant properties. Four samples of three brands were used; infusions of green tea (GT), 2 brands of black tea (BT), and a formulated herbal preparation for diabetes (ADT) (white tea, Radix Puerariae, Radix ophiopogonis, hawthorn berry, Chinese ya...

OBJECTIVE The present study was an attempt to study total phenolic content and antioxidant property of the crude ethanolic extract of the roots of Azadirachta indica (A. indica). MATERIALS AND METHODS To evaluate the antioxidant properties of the crude extract, some complementary test systems, namely DPPH free radical scavenging assay, reducing power assay, and ferrous ion chelating ability a...

Objective: The present study was aimed to find out antioxidant property of methanolic and aqueous extracts of Aegle tamilnadensis Abdul Kader (Rutaceae) leaf. Methods: The phenolic and flavanoid contents of methanolic and aqueous extract were determined. The antioxidant potential of the leaf samples was evaluated by using five in vitro assays such as 2, 2-diphenyl-1-picrylhydrazyl (DPPH), hydro...

background: thymus daenensis celak. is one of the medicinal plants which cultivated in iran. this plant involve high amount of polyphenols including thymol and carvacrol, which were reported to possess the high antioxidant activity. objective: antioxidative activity (aoa) and chemical constituents of thymus daenensis essential oil (tdeo) were examined. also, the effect of thermal treatments (80...

Haptoglobin (Hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. Hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. As an important consequence, Haptoglobin-Hemoglobin complex (Hp-Hb) shows considerable antiox...

The alcoholic extract of roots of Dichrostachys cinerea Wight & Arn. (200 and 400 mg/kg, p.o.) was studied for its protective effect against cisplatin-induced renal injury in rats. Cisplatin (6mg/kg, i.p.) significantly elevated serum markers level, increased urinary protein excretion, reduced urine to serum creatinine ratio and creatinine clearance. In curative regimen, the alcoholic extract e...

In the present study, an attempt has been made to evaluate the presence of antioxidant property in the alcoholic extract of Aloe vera leaf gel. Oral administration of Aloe vera gel extract at a concentration of 300 mg/kg to diabetic rats significantly decreased the levels of blood glucose, glycosylated hemoglobin and increased hemoglobin. The increased levels of lipid peroxidation and hydropero...

Chitosan is produced by deacetylation of chitin, the second most abundant polymer in nature next to cellulose. Being a unique cationic polysaccharide, chitosan possesses many functional properties and bioactivities, such as antioxidant property, lipidlowering activity, antimicrobial capacity, film-forming and gelling property, encapsulation potentials, and so on. Since last decade, it has been ...
